By screwing the bolt 21 to the anchor, it is firmly fixed on the road surface.

However, in the conventional lane control rod installed in this way, when a driving vehicle collides with the induction rod and an impact is applied, since the lower base 20 is integral with the induction rod 10, the induction rod ( 10), the lower part of the induction bar 10 is bent and easily broken by the impact applied to the rod, and accordingly, it is not uncommon for only the lower base 20 to remain as shown in FIG. 2(a). In addition, when a severe impact is applied, the force is transmitted not only to the lower base 20 but also to the anchor bolt 21 fastened to the lower base 20, so even the anchor bolt 21 is pulled out in severe cases. When the anchor bolt 21 is pulled out, a dangerous situation occurs as the anchor bolt 21 rolls on the road. That is, if the anchor bolts 21 are rolled under the tires of a vehicle in motion, the wheels of the vehicle in motion may be damaged, resulting in a serious traffic accident. There has been a problem that there is a high possibility of a dangerous situation causing great damage to other cars or pedestrians while going out.

A-A' partial cross-sectional view of 6 is shown, before (a) and after (b) the coupling of the cover 120 of the fixing base 200 and the induction rod 100 is shown. Hereinafter, detailed structures of the fixing base 200 and the guide rod 100 of the lane control rod according to the present invention will be described with reference to FIGS. 4 to 7 .

As shown in FIG. 4 , the fixing base 200 fixed to the road surface with anchor bolts 221 preferably includes a circular plate 210 . Further, it is preferable to include a plurality of bolt holes 220 into which the anchor bolts 221 are inserted in order to fix the circular plate 210 to the road surface G.L on the circular plate 210. In addition, it is preferable to form a plurality of coupling members 230 vertically protruding above the circular plate 210 on the circular plate 210, and at an upper end of each of the plurality of coupling members 230, It is preferable to form a coupling protrusion 240 protruding at right angles to the coupling member 230 . The fixing base 200 including the circular plate 210, the coupling member 230, and the coupling protrusion 240 can be firmly fixed to the road surface without being damaged, and the guide bar 100 It is more preferable to use a hard material with high durability so that it can be bonded stably.

On the other hand, as shown in FIG. 5, the induction rod 100 preferably includes a cylindrical main body 110 and a cover 120 connected to the lower end of the main body 110. Preferably, the cover 120 is integrated with the main body 110 and formed in a disk shape with an open bottom to cover the fixing base 200 . And, it is preferable to include a plurality of coupling holes 130 in the cover 120, the plurality of coupling holes 130, when the cover 120 covers the fixing base 200, Preferably, the coupling protrusion 240 is formed at a position corresponding to each of the plurality of coupling members 230 so that the coupling protrusion 240 can be inserted into and coupled to the coupling hole 130 . Therefore, when the cover 120 formed in a disk shape under the induction rod 100 is coupled to the fixing base 200, the coupling protrusion 240 formed on the coupling member 230 forms the coupling hole 130. and is caught on the cover 120, so that the lower part of the induction rod 100 can be firmly coupled to the fixing base 200.

As described above, the fixing base 200 including the circular plate 210, the coupling member 230, and the coupling protrusion 240 is made of a highly durable hard structure so as to be firmly and stably fixed to the road surface. It is preferable to use it as a material. However, in the case of the induction rod 100, it is preferable to use a soft material having elasticity and stretchability. In this case, when the cover 120 is coupled to the fixing base 200, the cover 120 can be smoothly coupled using elasticity and elasticity of the cover 120. In addition, when a force below a certain limit is applied by an impact of a vehicle or the like in a state where the lane control rod is installed on the road surface, the cover 120 at the lower end of the induction rod 100 provides elasticity and elasticity. Since the branch is made of a soft material, it is not easily broken even if it is bent, and can be immediately restored by elasticity when the force caused by the impact is removed. In addition, when a force exceeding the limit is applied to some extent, the cover 120 separates from the fixing base 200 to prevent damage or separation of the fixing base 200 or the anchor bolt 221. there will be

On the other hand, when the induction rod 100 and the fixing base 200 are coupled, the shapes of the coupling member 230, the coupling protrusion 240, and the coupling hole 130 are changed in order to maintain a stable coupling state. It is preferable to form a concentric circle with the circular plate 210 . To this end, the cross section of each of the coupling members 230 viewed from above has a closed arc shape concentric with the circular plate 210, and the shape of each coupling hole 130 viewed from above, and the coupling member 230 It is desirable to have the same shape as the cross section seen from above. Further, each of the coupling protrusions 240 preferably protrudes from the upper end of the coupling member in the circumferential direction of the circular plate.

It is more preferable to make it slightly different from the circular arc shape. That is, the cross-section of each of the coupling members 230 viewed from above is made to have a closed arc shape concentric with the circular plate 210, but the size of the arc gradually decreases toward the outer circumferential surface of the circular plate 210.

It is desirable to make it a shape. However, the shape of each of the coupling holes 130 viewed from above is a concentric circular arc shape with the circular plate 210, but both ends are round.

It is desirable to make it a shape. In addition, each of the coupling protrusions 240 has the same size as the outer circumferential surface of the coupling member 230, and the size of the arc gradually increases in the circumferential direction of the circular plate 210. It becomes smaller, so the shape seen from above

It is preferable to make it into a shape. In addition, each of the coupling protrusions 240 has a groove 241 opened toward the circumferential direction of the circular plate 210 at the center thereof, so that each coupling protrusion 240 has a top view.

It is more preferable to make it into a shape. The groove 241 formed in the coupling protrusion 240 is a means for easily assembling and disassembling by inserting a tool such as a screwdriver.

In addition, it is more preferable to have a stepped portion 140 connected to the coupling hole 130 outside the coupling hole 130 . The stepped portion 140 is connected to the side of the coupling hole 130 toward the outer circumferential surface of the cover 120, the depth of the stepped portion 140 is equal to the thickness of the coupling protrusion 240, and the stage It is preferable that the shape of the jaw portion 140 viewed from above is the same as the shape of the coupling protrusion 240 viewed from above. In this case, since the coupling protrusion 240 does not protrude to the upper surface of the cover 120, it is possible to maintain a smooth appearance.

On the other hand, Figure 8 shows a state in which the coupling hole formed in the cover is deformed when an impact is applied to the guide bar of the lane control bar according to the present invention, Figure 8 (a) is a plan view viewed from above, Figure 8 (b) ) is a cross-sectional view from the side. Hereinafter, referring to FIG. 8 , an operation principle when an impact is applied to the lane control bar according to the present invention will be described. As shown in FIG. 8, when a vehicle or the like collides with the main body 110 of the induction rod 100 and a force F due to the impact is applied, the induction rod 100 rotates at an angle equal to the magnitude of the force F. (θ) is inclined, and accordingly, a lifting force f1 is applied to the part on the opposite side of the pushing direction of the cover 120, but by the coupling protrusion 240 at the top of the coupling member 230 Being held back, the lid 120 does not lift and remains in place. However, since the cover 120 is made of a stretchable and elastic material, the coupling hole 130 is stretched and deformed by the force applied while the induction bar 100 is tilted. As shown in FIG. 8 (a), the front The portion is stretched and stretched in a shape similar to 130a. Therefore, the induction rod 100 is bent by the elasticity of the cover 120, and when the force due to the impact is removed, the coupling hole 130 is stretched and restored to its original state by the pulling force like a rubber band. However, if the force applied to the induction rod 100 is too great and exceeds the tensile limit of the cover 120, the cover 120 is torn and damaged, so that the induction rod 100 is separated from the fixing base 200. will depart However, the fixing base 200 can remain intact without being damaged.

Therefore, in the lane control rod according to the present invention, when an impact is applied within a certain limit, even if the induction rod 100 is bent due to the elasticity and elasticity of the cover 120, when the force caused by the impact is removed, the cover It is immediately restored by the elasticity of 120, and when a force due to excessive impact is applied, the fixing base 200 is not damaged and only the guide rod 100 is damaged, so there is a danger due to the separation of the anchor bolt. etc. can be prevented, and maintenance can be performed by coupling only the induction rod 100 without the need to replace the fixing base 200, thereby reducing maintenance costs.

Although the present invention has been described with the various examples described above, the present invention is not necessarily limited to these examples, and may be variously modified and implemented without departing from the technical spirit of the present invention. Therefore, the examples disclosed in the present invention are not intended to limit the technical idea of the present invention, but to explain, and the scope of the technical idea of the present invention is not limited by these examples.
